Or you may say: "On what will be best for the creditors." (Obviously, creditors' interests go beyond Greece paying its debts. Creditors do take into account how financial markets will react to the different outcomes in this endgame between Greece and its creditors -- see, eg, this article for investor sentiment: "The opportunity in Greece crisis". They also take into account (geo)political consequences -- see, eg, "Geopolitics Will Trump Economics in Greece".)

However, I doubt that what is considered to be the best outcome for the creditors (that Greece accepts its conditions) really is the best outcome for the creditors.

About Me

As a kid I liked numbers and the sound of strings. I considered studying engineering but chose social sciences because of my interest in people. I combine a theoretical interest with a practical, social approach which brought me to the sphere of policy research. I am interested in reducing the disparity between poor and rich, between the powerful and the less powerful.
In 1973 and 1982 I lived in Latin America. In the mid-1980s, I was able to create an international forum to discuss the functioning of the international monetary system and the debt crisis, the Forum on Debt and Development (FONDAD). I established it with the view that the debt crisis of the 1980s was a symptom of a malfunctioning, flawed global monetary and financial system.
I was one of the driving forces behind the creation of the European Network on Debt and Development that was established at the end of the 1980s to help put pressure on European policymakers.
In 1990, before the beginning of the Gulf War, I cofounded the Golfgroep, a discussion group about international politics comprising journalists, scientists, politicians and activists that meets regularly.
